Hi perfs,

I'm having problems when loading textures in TRAM. The application runs on an
Octane with 4MB TRAM. As long as there's available TRAM, the application runs
fine, but the moment a scene uses all available texture memory, the application
exit sending an OUT OF MEMORY message. This message is sent from libGLcore.
When all texture memory is used, shouldn't GL start paging stuff ??

Does anybody know what causes this ??

Thanks in advance for any hints.

Jean-Luc.

Here's the trace I get from dbx:
